(3+v)+(2v^2)=0

Solution for (3+v)+(2v^2)=0 equation:

Simplifying
(3 + v) + (2v2) = 0

Remove parenthesis around (3 + v)
3 + v + (2v2) = 0

Solving
3 + v + (2v2) = 0

Solving for variable 'v'.

Begin completing the square.  Divide all terms by
2 the coefficient of the squared term: 

Divide each side by '2'.
1.5 + 0.5v + v2 = 0

Move the constant term to the right:

Add '-1.5' to each side of the equation.
1.5 + 0.5v + -1.5 + v2 = 0 + -1.5

Reorder the terms:
1.5 + -1.5 + 0.5v + v2 = 0 + -1.5

Combine like terms: 1.5 + -1.5 = 0.0
0.0 + 0.5v + v2 = 0 + -1.5
0.5v + v2 = 0 + -1.5

Combine like terms: 0 + -1.5 = -1.5
0.5v + v2 = -1.5

The v term is v.  Take half its coefficient (0.5).
Square it (0.25) and add it to both sides.

Add '0.25' to each side of the equation.
0.5v + 0.25 + v2 = -1.5 + 0.25

Reorder the terms:
0.25 + 0.5v + v2 = -1.5 + 0.25

Combine like terms: -1.5 + 0.25 = -1.25
0.25 + 0.5v + v2 = -1.25

Factor a perfect square on the left side:
((v) + 0.5)((v) + 0.5) = -1.25

Can't calculate square root of the right side.

The solution to this equation could not be determined.
